1 Claim. 1

This invention relates to improvements in dough fanning machines andmore particularly to a novel device for the prebaking forming ofcrullers or stick doughnuts.

An object of the invention is to provide a device of the type which willaccurately form the dough elements adapted for the baking of crullerswithout the use of dies now present in devices of the type inpresent-day use.

Another object of the invention is to provide a device which is capableof varying the size and shape of said elements, which is not possiblewith the die equipped machinery.

Another object of the invention is to provide simple and efficient meansfor the dusting of flour on the elements in the forming process.

Other and further objects of the invention will be apparent as thedescription proceeds, reference being had to the accompanying drawings,in which:

Fig. 1 is a side view of a dough forming machine embodying my invention.

Fig. 2 is a plan view of the same.

Fig. 3 is an end view of one .of the flour sifting devices.

Fig. 4 is a plan view of the same.

Fig. 5 is a front fragmentary view of one of the leveling boards and theadjustment control therefor, partly in section and partly in elevation.

Fig. 6 is a side detail fragmentary view of the control link andleveling board, together with a portion of the canvas beltand one of thedrums mounting the same.

Fig. 7 is a detail front view of the dough extruding device and therotatable dough cutter element.

Referring more particularly to the drawings, the number It! refers tothe device generally, having a frame ll having supporting legs l2. Rearshield members l3 journal the axle l4 on which is mounted the drum I5.Front shield member It journal the axle l1 carrying the drum member iii.A canvas belt I9 is carried about the said drums l 5 and I8 and thetightener roll 26. The front legs I 2 carry the tightener rods 2! theinner ends of which 22 journal the roll 20, and which are provided attheir outer ends 23 with the threaded tightening means 24. A pair ofguides 25 are fastened to the frame II by the brackets 25 and aredisposed parallel 2 to and adjacent the side edges of the belt [I9 andconstitute a side guard for the leveling board 21. The board 21 is heldabove and away from the belt l9 by the transverse angle irons 28 whichare secured to the reversed angle irons 29 which latter are notchedcentrally at 30 to receive the flexible coupling 3| comprised of rings32 and 33, the spring 34 and nut 35 on the vertically adjustable rods 36threaded in the supports 3! at 38 thereof and operable by the handles39.

A dough extruding device 40 is mounted on frame I l by means of thebracket 4|, and may be of any convenient type, and is actuated by thepower shaft 42 operated by suitable motor means. A gear 43 on shaft 42operates a gear 44 on shaft 45 which operates the rotatable cutterelement 45 having a, pair of arcuate arms 41 and 48, and a cutter wire49 connecting the end 50 of arm 48 with the shaft 45.

A bracket 5| fixed above the rear support 3'! holds a flour sifter 52above the orifice at 53 of the extrusion device 40. A spring element 54is affixed to the bottom of the sifter 52 and protrudes into the path ofthe arms 41 and 48 on the cutter element 46.

An apparatus for sifting flour on the surface of the belt l9 comprises astationary screen receptacle 55, having a one-piece bottom and sides ofthe screen 55 and the end plates 51, in which are journaled the cranks58 connected by an agitator rod 59. The axle 60 of one of the cranks 58is fixed to the outside crank 6|, which latter is coupled by means ofthe connecting rod 62 to the crank 63 fixed to the axle l4.

In operation, the same motor which actuates the shaft 42 operates theaxle l4 mounting the drum l5. As the dough 65 is extruded from theorifice at 53 the rotating wire 49 severs small portions thereof, andthe arms 41 and 48 impinging against the spring element 54 willprecipitate intermittently small portions of flour on said portions asthey fall on the belt l9 to be carried toward and under the shaping orleveling board 21. The handles 39 are adjusted to hold said board at thedesired height, and. the portions of dough will acquire a cylindricalform especially adapting them to be baked as crullers. As they pass overthe drum is on belt 19 the said cylindrical member 66, from which theymay be appropriated for the baking operation.

Having thus described my invention, it will be understood that thedevice is capable of many modifications in structure and design, withoutdeparting from the spirit of the invention, within the scope of theappended claim.

What I claim and desire to secure by Letters Patent of the UnitedStates, is:

In a device of the character described, means for extruding dough incontinuous cylindrical form, a rotatable shaft adjacent said extrusionmeans, an arcuate member centrally fixed on said shaft, a, wine; cutterelementgextended from one end of said arcuate member to said shaft forintermittently cutting through said extruded.

dough, a flour sifter mounted above said extrusion means, and ayieldable member on.
